HEATING-STOVE.

SPECIFICATION forming part of Letters Patent No. 310,904, dated January20, 1885.

Application filed Apr-i121, 1884. (No model.)

T 0 all whom it may concern.-

Be it known that I, P. K. MoMINN, of Be ment, in the county of Piatt andState of Illinois, have invented certain new and useful Improvements inHeating-Stoves; and I do hereby declare the following to be a full,clear, and exact description of theinvention, such as will enable othersskilled in the art to which it pertains to make and use it, referencebeing had to the accompanying drawings, which form part of thisspecification.

My invention relates to an improvement in heating-stoves; and itconsists in the combination of a chamber which is formed upon the top ofthe stove itself, and through which the air to feed combustion ispassed, a suitable number of vertical pipes which connect with thischamber and which pass down through the fire-chamber and the hot-airchamber in the base of the stove, and from which chamber the air escapesinto the fire-chamber for the purpose of feeding combustion, all ofwhich will be more fully described hereinafter. V

The object of my invention is to heat the air very thoroughly before itis fed to the fire, and thus cause a more perfect combustion than can beobtained where the air is fed in cold.

In the accompanying drawings, Figure 1 represents a vertical section ofa heatingstove embodying my invention. Fig. 2 is a detail view showinghow the basket is supported.

A represents the body of the stove, which will be of any desired size,shape, or construction that may be preferred, and upon the top of whichis placed the cap or cover B. This cap or cover extends a suitabledistanceabove the top of the stove itself, so as to form an airchamber,0. Through the top of this cover B are made a suitable number ofperforations through which the air passes. Secured to the perforated topof the stove are a suitable number of hot-air pipes, E, which pass downthrough the fire-chamber and through its bottom H. These pipes serve thedouble purpose of conveying the air which is to support combustionthrough the fire-chamber, where base of the stove, and forming supportsfor the grate in which the fire is built. Suitable cross-bars, J, extendacross from pipe to pipe, and upon these cross-bars J the grate issuspended. This grate being placed between these pipes and almost incontact with them, they are kept heated as long as there is any fire inthe grate, andthus made to heat the air which is passing through them.The air passes into the chamber L in the base of the stove, and fromthence passes through the opening N back into the firechamber, under thegrate, for the purpose of feeding combustion. The air passing up underthe grate in a highlyheated condition produces a much more perfeetcombustion than can take place where the air is fed as has beenheretofore proposed. By thus feeding hot air to the fire not only is amore perfect combustion produced, but the same stove can be made to burnhard and soft coal, wood, or fuel of any kind.

I am aware that a heating-drum for the incoming air has been placedinside of the stove, and that pipes have been connected to the drum,passed through the sides of the stove, and connected at their lower endsto the chamber in the base of the stove, and this I disclaim.

Having thus described my invention, I claim-- In a heating stove, thecombination of the body A, the perforated cap B, the chamber 0, and thehot-air pipes which pass down through the fire'chamber and into thechamber in the base of the stove to supply air beneath the grate, theparts being combined andarranged to operate substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
